Ernst Georg Pritzel was a German botanist.
He is known for his research in the fields of phytogeography and taxonomy. He contributed works on Lycopodiaceae, Psilotaceae and Pittosporaceae to Engler & Prantl’s "Die Natürlichen Pflanzenfamilien".
In 1900–02, with Ludwig Diels, he collected plants in South Africa, Australia and New Zealand. They published the results of their expedition in the Botanische Jahrbücher in 1904–05. Their findings included 235 new species.
The fungi genus Pritzeliella was named after him by Paul Christoph Hennings in 1903 and Melaleuca pritzelii by Karel Domin in 1923.
